15 mL Autoanalyzer Cups, PS, Green, BD® Compatible — 240-6400-G10 | 4/Bag | Caplugs® Evergreen

Multi-Tier Universal Lab Racks — Polystyrene (PS), Green, 4/Bag

Technical Narrative

The Caplugs® Evergreen 240-6400-G10 is a multi-tier universal lab rack precision-molded from virgin Polystyrene (PS) for benchtop organization, centrifuge staging, and sample management across laboratories that work with multiple tube formats simultaneously. Unlike single-diameter racks that require separate purchases for each tube OD, the multi-tier slot design accommodates test tubes, 15 mL and 50 mL conicals, microcentrifuge tubes, blood collection tubes, transport vials, and specimen cups across different tiers — consolidating multiple rack SKUs into one versatile benchtop footprint. The green PS construction means green signals safety or completed-status tube management in color-coded laboratory workflow systems.

Virgin PS construction delivers autoclave compatibility at 121°C, UV decontamination compatibility for biosafety cabinet workflows, and broad chemical resistance to standard laboratory disinfectants and aqueous reagents. PS rigidity ensures rack geometry is maintained under full tube loads without flex or slot-width creep that can cause tubes to seat unevenly or tip under centrifuge staging vibration. The multi-tier slot geometry distributes tube weight across multiple contact points per tube, reducing OD wear-induced loosening over the rack service life.

At $28.06 per 4/Bag — $7.0134 per rack — the delivers universal tube organization at a per-unit cost that enables dedicated rack-per-benchtop allocation without reuse scheduling overhead. Also available in: 240-6400-B10 (Blue, $28.06/Bag); 240-6400-Y10 (Yellow, $28.06/Bag) — enabling full color-scheme procurement from a single vendor for multi-user bench labeling systems.

Technical Specifications — Caplugs® Evergreen

Compatible Tube Formats —

The multi-tier design accommodates a wider range of tube diameters than single-diameter racks, making it the default choice for mixed-tube benchtop environments. Validated compatible formats:

Multi-tier racks hold tubes by OD friction-fit. Always confirm tube OD against slot width before large-volume purchase. Request a free sample to validate fit with your specific tube formats.

Chemical Resistance — Polystyrene (PS)

The is molded from virgin Polystyrene (PS). PS delivers excellent resistance to standard aqueous lab reagents and alcohol-based disinfectants. Avoid acetone and chlorinated solvents.

Clinical & Research Laboratory Applications

The multi-tier universal rack serves clinical chemistry and hematology benchtops managing mixed tube assay panels; molecular biology labs running simultaneous PCR, extraction, and quantification workflows requiring multiple tube ODs at a single workstation; hospital STAT labs staging blood collection tubes alongside serum separator and transport vials; biorepository accessioning desks processing diverse tube formats from multiple collection sites; pharmaceutical QC benches handling both microtubes and larger-volume conical formats; and educational laboratories where a single rack type must serve multiple experiment formats. The 4/Bag format supports multi-bench deployment at economical per-unit cost.

Frequently Asked Questions — Caplugs® Evergreen

What tube sizes fit the multi-tier universal rack?

The multi-tier design accommodates multiple tube OD ranges across its tiered slot positions simultaneously, including: standard test tubes (10–16 mm OD), 15 mL conical tubes (17 mm OD), blood collection tubes (13 mm OD), microcentrifuge tubes (11 mm OD), transport vials, and specimen cups. The tiered slot geometry means different tube diameters can occupy different tiers on the same rack — request a free sample to validate fit with your specific tube OD before large-volume purchase.

Can the rack be autoclaved between experiments?

Yes. The is molded from virgin Polystyrene (PS) and is autoclave-compatible at 121°C / 15 psi for decontamination between experiments. PS is also compatible with standard 254 nm UV decontamination cycles in biosafety cabinets and clean-bench environments. Avoid acetone and chlorinated solvents — PS is sensitive to these reagents.

Are the racks BPA-free and phthalate-free?

Yes. The is molded from virgin Polystyrene (PS) containing no BPA and no phthalate plasticizers — suitable for clinical, research, and regulated laboratory environments where material purity matters.
